Z Start
![]()
This is the Z-axis work coordinate where the threading operation begins.
Z End
![]()
This is the Z-axis work coordinate where the threading operation ends.
Minor Diameter
![]()
This is the smallest diameter of the thread.
For internal threads, the minor diameter is measured from crest to crest.
For external threads, the minor diameter is measured from root to root.
Minor diameter values can be found in standard threading charts and machinist handbooks.
